To all whom it may eon-m.-

Be it known that we,

Conmmogcitizens of the United States, re siding at Okmulges, in thecounty of Okmulgee and Stzitcof Oklahoma, have invented certain new anduseful Improvements in Wrenches, of which the following is a specfication.

. the co-pendin application serial Number tenses, end ccmlcer 18th,1912, of Anton T. Anderson. v

-The object of the present device is the provision oi: e wrenchcomprising an adjusteble heed lmonnted u on ehandle, with means 101'controlling t .e movement of said head whereby the latter may he held ina stationary position or upon initial move mont of e controlling memberto permit fnee swinging movement'of the head and upon continuation ofthemovement ofsaid controlling member to limit the swing of the headotoone direction onl To this end our wrench is provided wit heed engagingstationary with which members a control-' members normally tending tohold the same ling lever cooperates in a manner which will be moreclearly understood as this. description roceeiis. i

With the above and other objects in view, this invention consists injtheconstruction, combinationnnd arrangement of parts all as hereinaftermore fully described, claimed and illustrated in the accompanying drawins, whereinhead engaging members to permit ratchet movement of the.headon its pivot in either direction. Fig. 5 is a fragment r'y viewshowing more clearly the intcrme iete position assumed by the pawlsunder action of the controlling lever.

The means for controlling movement of this head 3 is-di's =d betweenthe head'and the handle 1, an also between the arms 2, as clearly shownby reference to Figs. 2, 3 and 4 of the drawings.

Said means consists of a; pair of head on v gaging members or pawlslispaced apart so as 'to engage the ratchet teeth 5 of the head atopplnsite sides of the same. Each which is disposed between the oppositeends of the pew-ls in en epettored partition 15. This spring isilonislly under compression for this purpose and the penis 14. arepreferably formed with seats 16, shown in Pig:

To ermit ratchet movement of the head in t e opposite direction.the lever pawl is moved in the reverse direction to that above describedas will be clearly understood. by those skilled in the art to which thisrefers.

It will be apparent from the foregoing that this arrangement of thecobperating parts of the wrench 'is distinctly advantageous when it -isused to manipulate a nut in a place comparatively difiicult to permitoffree access, because of the fact that it is not necessary to remove-the wrench head I from engagement after it has once been aplied to turnthe nut in either direction. 1: is also particularly desirable that thewrench head be normally held stationary and susceptible-of control foruse as a ratchet wrench as well as allowing the headto be fixedlypositioned at various angles with respect to the handle when so desired.

With the foregoing in View it is obvious, referring to Fig; 3, that theinitial'movement of the controlling lever 19 will operate the spacedpawlsso as to bring themvinto the dotted line positionshown in saidfigure and that the continued. movement of the old in a stationaryposition. by the.
